# Quality

Quality is one of the three OEE components and shows what proportion of the produced quantity meets quality requirements.

{% hint style="info" %}
What quality means in the OEE context and how it is calculated is explained under [Quality (Concepts)](/en/concepts/understanding-oee/quality.md).
{% endhint %}

## Prerequisites

For ENLYZE to calculate quality, the following data must be available:

* **Performance tracking** is set up (see [Setting up OEE tracking](/en/production-optimization/oee.md))
* **Order data** is connected to ENLYZE (see [IT-Connectivity](/en/connect/it-connectivity.md))
* **Good quantity or scrap quantity** is reported per order

## Tracking good quantity and scrap

ENLYZE calculates raw material consumption from throughput and runtime of an order. Depending on which data is available, there are two paths to quality calculation:

**Good quantity is reported**\
ENLYZE calculates scrap as the difference between raw material consumption and good quantity.

**Scrap is reported**\
ENLYZE optionally distinguishes between startup scrap and running scrap, provided this distinction exists in the source system. The good quantity is calculated as raw material consumption minus scrap quantity.

{% hint style="info" %}
The type of quality data tracking is determined during integration. Contact your ENLYZE representative to discuss the appropriate configuration.
{% endhint %}

## Quality in the app

The quality KPI is shown in several places in the ENLYZE App:

* **Order details**: For each order, good quantity, scrap, and quality factor are displayed.
* **Product overview**: The material overview shows lot size and scrap across all orders of a product (see [Setup sheet](/en/production-optimization/setup-sheet.md#material-overview)).
* **Home screen**: The OEE summary includes the quality factor.
